CORNER-READ.

Application filed May 21, 1917.

Too whom it may concern Be it known that I, NORRIS ELMORE CLARK, a citizen ofthe United States of America, residing at Plainville, Conn, have invented ainew and useful Corner-Bead, of which the following is a specification.

"My invention relates particularly to the so-called cli type of bead. The main object is to-provi e a construction which can be made cheaply and yet which is strong and rigid, readily erected and aifords a secure key for the. plaster.

In .its preferred form the body of the head is made of sheet metal folded and shaped so as to have a rounded nose with lateral under cut shoulders. The sides are preferablybrought'tojgether immediately back of thesels'houlders and .then spread outwardly and-the edges brought toward each other so as toformlongitudinal ribs. Between the indented side/sand the rib parts of the metal are cut longitudinally and turned inwardly so as to formlong, narrow slots and produce under-cut recesses. Through these nar row slots attaching clips are inserted and bent to fit the corner to which the bead is to be attached. These clips are preferably provided with longitudinal slots at the points where the clips engage the longitudinal member of the bead so as to provide passages for the cement or plaster and thus insure the better binding together of the parts. The slot is only slightly wider than the thickness of the metal so that when the clip is bent the parts will bind and prevent the accidental displacement of the clip. in the process of assembling and erection. Preferably the edges of the bead are bent toward each other at points between the clips so as to afford additional under-cut pockets for the reception of the plaster or mortar.

Figure 1, is a side view of a bead embodying the improvements of my invention showing also in dotted lines the position of a clip bent diagonally to accommodate attachment at the erection point.

Fig. 2, is a rear view of the body showing in dotted lines the possibility of moving the clip longitudinally of the bead to a limited extent.

Fig. 3, is a horizontal section on an enlarged scale showin a fragment of the clip inserted but before ending.

b Fig. 4, is a similar View showing the clip ent.

Serial No. 169,841.

Figs. 5 and 6 are face views of a fragment of a clip showing modifications of details.

Figs. 7 and 8 are edge views of fragments of 1clips showing other modifications of detai s.

The nose 10 may be of any desired shape but is illustrated herein as rounded and provided with shoulders 11 11 which are so shaped as to provide unc er-cut recesses 12, 12. The sides 18 are preferably bent together to'form a central member which is adapted to project outwardly from the angle of the wall. The slots 14, 14 are formed by slitting the metal longitudinally and bending-the-flanges 15 inwardly so as to form under-cutpockets 16. The walls 17 between the slots are bent outwardly and longitudinallyextendin'g'ribs 18 are formed extending continuously parallel to the shoulders 11. The rear edges are twisted alternately to the right and left so asto form flanges 19 which extend toward'each other. This forms a continuous .pocket in the rear of the bead of irregular cross section,'the part 21 being deeper than the part 22.

The clips 23 are preferably formed of flat strips of metal somewhat thinner than the width of the slots 14 and somewhat narrower than the length of the slots 14 in the body of the bead. Preferably the clips are provided with central slots 24 so as to permit the plaster or cement to pass through at this point and more closely embed the clip and the body of the bead at the point of connection. This also weakens the clip at this point and thus enables it to be more readily bent together after it is inserted. When the clip is bent as shown in Fig. 4 it will be noted that the central part 25 arches slightly so as to fill in the slot in the body of the bead and prevent shifting of the clip. The slots 14 are preferably formed at frequent intervals and clips may be inserted in any number of these slots at such intervals as desired. The clips may be adjusted up and down as indicated in dotted lines in the lower part of Fig. 2 or they may be twisted as indicated by the dotted lines in the lower part of Fig. 1 so as to bring the nail openings 26 at the point best sulted for attachment to the corner.

The clips may also be notched as at 27 in Fig. 5 or at 28 in Fig. 6 so as to insure the bending of the clip at the exact point desired. When the notches are on the outer edges as in Fig. 5 the notches may serve to engage the body of the bead and prevent shifting of the clip therein. The clips may be also provided with a number of corrugations as shown at 29 and 30 in Figs. 7 and 8 so as to engage parts of the body of the bead to prevent relative shifting of the clips. The corners 28 adjacent the notches 28 may be turned up as shown in Fig. 6 to engage the body of the bead and hold the clip if desired.

What I claim 1. A corner bead construction having a nose and lateral shoulders with side recesses and narrow longitudinal slots and outwardly flaring portions forming ribs at the edges, the sides of the slots having inturned flanges and the edges of the ribs being bent to the rear so as to form in conjunction with the flanges a longitudinally extending pocket of irregular cross sectional shape.

2. A corner bead construction comprising a body having a nose with side shoulders, indented sides, outwardly flaring walls with narrow longitudinal slots, inturned flanges at the edges of the slots and rearwardly extending edges twisted alternately in opposite directions and forming a longitudinal pocket of irregular cross sections at the rear.

3. A corner bead construction comprising a body having a nose with side shoulders,

indented sides, outwardly flaring walls with narrow longitudinal slots, inturned flanges at the edges of the slots and rearwardly extending edges twisted alternately in opposite directions and forming a longitudinal pocket of irregular cross sections at the rear in combination with attaching clips extending through some of said slots and arched at their central portions to engage the body of the bead along a central line at the crown of the clip and along two lines at opposite sides thereof.

4. A corner bead construction comprising a: body having longitudinal shoulders, indented sides and outwardly flaring edge portions with slots between said edge portions and said sides, said slots being arranged in pairs, the slots of each pair being spaced apart laterally to form pockets between the outwardly flaring edge portions in combination with clips arranged in some of said slots, each clip having a central opening with metal on each side thereof whereby the plaster or cement may pass through the central openin and into the slot containing the clip and t e pocket in rear of the out wardly flaring edge portionsto reinforce the rear of the body and hold the clip in place;
